PATENT CURETTE.

SPECIFICATION forming part of Letters Patent No. 651,395, dated. June 12, 1900.

Application filed $eptemher 26, 1899. Serial No. 731,761- (No model.)

To all whom it ntoty concern.-

Be it known that I, MILoR-oB STAPP, a citizen of the United States, residing at Aberdeen, in the county of Ohehalis and State of Washington, have invented a new and useful Surgical Instrument, of which the following is a specification.

This invention relates to surgical instruments, and particularly to that class known as curettes; and the primary object in view is to provide a simple and effective device of this character that is easily insertible and withdrawable in and from the vagina and uterus without injury or excoriation and adapted .for use in removing diseased tissues or remnants subsequent to abortion or miscarriage or any inflamed condition the uterine lining is prone to take on and become involved in and also capable of reduction in size to accommodate variations in the natural proportions of different organs and changes in dimension due to diseased conditions and sympathetic responses of parts adjacent the main affected organ.

The secondary object is to have the improved device so arranged that it may be readily separated into distinct parts for cleansing and also to form it of such material as to permit thorough sterilization to avoid poisonous transmissions.

The invention consists in the construction and arrangement of parts hereinafter more fully described and claimed.

In the drawings, Figure 1 is a perspective View of the improved device arranged for use. Fig. 2 is a longitudinal vertical section of the improved device arranged for withdrawal.

Similar numerals of reference are employed to indicate corresponding parts in both views.

The numeral 1 designates a stem preferably formed in rod shape of proper diameter and length and having the rear terminal screw-threaded, as at 2, to removably receive a handle 3 of polygonal form for convenience in grasping and operating the instrument as an entirety. On the front end of the said stem intersecting scraping-loops 4 are fixed in a suitable manner and one made smaller than the other and closely fitting therein. It is obvious that the number of these loops may be varied, and to render them effective they are constructed of thin high-grade steel,

tremities to conform to the dimension of a uterus in normal condition. The opposite edges of the loops provide means for loosening and cleaning the uterine lining, and the position of the said loops afford means for withdrawing the loose matter from the uterus and out through the vaginal canal.

The stem-1 is slidingly mounted in an elongated sleeve 5, having a sheath 6 on its outer end to partially or wholly receive'the loops 4 for the purpose of adjustment or inclosure of the latter. The sheath is moved over the loops to contract them and regulate their lat eral projection to accommodate variations in the size of different uteri under inflamed or swollen conditions and to position the said loops with ease in operative relation to a sensitive uterine lining. At times the loops may be entirely inclosed in the sheath during insertion and withdrawal. When the loops have been properly positioned in the uterus, they are caused to effectually perform their desired function by rotating them by means of the handle 3, located exteriorly; all the parts being proportioned in such manner as to locate the said handle far enough outward for convenient manipulation.

In cleaning or sterilizing the instrument the handle 3 is disconnected from the stem 1 and the sleeve 5, with its sheath, is slipped off the screw-threaded terminal 2.
